Wiring a 5 amp lamp circuit

Postby gizmo » Sat Nov 17, 2007 10:15 am

When wiring a standard lamp socket (5 amp), is it OK to wire several sockets in series without looping back? This will be on lighting circuit not ring main. Thank-you.

Simply Build It

Hi Gizmo,
I take it you want to install a circuit for outlets for standard lamps ect rather than ceiling roses? using 3 pin 5A sockets, if so then fine as a radial with no need to return to C.U.
However if you are creating a new circuit then it is a controlled installation under bldg regs 'Part-P' see 'Projects'

So if a new consumer unit and/or a lighting circuit is fitted for upstairs or downstairs are you saying new regs mean a ring circuit for lighting similar to a ringmain?

i.e. start and finish at CU?

Radials for lighting
Rings for 13 amp power,ie sockets etc, only

2 or 5 amp type sockets only allowed on lighting circuits, fused at 6 or10 amp max at supply fuse.

These sockets usually wired back to each room ceiling rose, usually 1.5 cable as a radial so the existing room switch will work the lights.
Subject to total lamp load and possible part p work.

You can wire them to the fusebox (Radial 1.5 cable),but each light will then need its own switch fitted, so you might as well put twin power sockets in which could be used for other stuff as well.(ring or radial 2.5)
Also possible part p work
